Original application filed May 7, 1924, SeriaI No. 711,581. Divided and this application fil ed February 15,

i 1927. Serial My invention relatesto looms and more particularly to looms in which the shuttleis passed back and forth through the warp shed on'inversely reciprocating carriers and has for its object to provide a novel and simple coupling mechanism whereb the shuttleis automaticall connected wit and disconnected from sai carriers in alternate sequence. The invention will be fully de scribed hereinafter and the features of novelty will be pointed out in the claims. The present appl cation is division of an other aoplication filed by me in the United States atent Office, on May 7 1924, Serial No. 711581, issued on April 5, 1927 as-United States Patent No. 1,623,258.

In the accmnpanyin drawings, which illustrate an example 0? the invention without defining its limits, Fig. 1 is a front elevation of a loom embodyingthe novel features; 1 Fig. 2 is a fragmentar front'view showing the invention on an en a'rged scale; Fig. 3 is aplan view thereof, and Fig. 4 is a section on the line 44of Fig. 2.

The loom comprisesa support or frame of conventional construction upon which the operatin elements of the loom are mounted as s hown in l ligqhand which is provided with guiding devices along which carriers for the shuttle are slidabl reciprocated to pass said shuttle backwar and forward through the warp shed. In the form shown in the drawings, the guiding devices comprise rods 16, properly located in the loom, on which the carriers 17 and 17 are slidably mounted. The carriers 17 and 17 are connected by means of links 18 with rocking armsl9 pivotally mounted at 19 upon the support 15 and in turn connected by means of rods 20with oppositely disposed cranks 21 forming part of a crank-shaft 22. The latter is journalled on the frame 15 and is operated in any conventional manner to bring about an operation oi'the parts. The carriers are provided with arms 23 and 23" respectively arranged in pairs uponsaid carriers and adapted to alternately support the shuttle 24 in its travel back and forth through theshed. Inaddition to the parts so far described, the carriers are provided with rocking arms 25 and 25 respectively. pivoted at 26 and having one end connected at 27 and 27 with slidable members 28 and 28 respectively. Otherends of 'the arnrs25 and 25 are pivotaily connected with n-i] ping members 29 and 29 respectively, said members being provided with a plural'ity of notches 30 and 30 adapted to be engaged by resilient members 31 and 3l to maintain the members 29 and 29 in adjustedpositions, as w1ll appear more fully hereinafter. The carriers are :turther provided respectively with coupling hooks 32 and 32 adapted ior engagement with the ends 33 and 33 of a locking latch in the form of a pivoted lever fulcrumcd at 35 upon the shuttle 2% as shown in Fig. 2. The lever 8d is provided at its opposite ends with inclined surfaces 36 and 36" adapted to cooperaterespectively with correspondingly inclined ends "37 and 37 of the members 29 and29 Atfa central: point, the loom is provided with a rocking mentwith the hook 82 by reason of't'lie "fact that the inclined end 37 of the member 29 is in positive engagement'with the inclined surface 36 of the locking latch. At this stage, the end, 33 of the locking latch is above andconsequently disengaged from the. hook 32?, sothat the carrier 17finterp0ses no interference to this movement of the shuttle. by the carrier 17, The connection between. the shuttle and the carrier17 through the. medium of the'hook 3..and the ei1df33 .is maintained throiiighout thereturn movement of the shuttle toward the right, in this case until the carriers reach their extreme inner positions. By the time this point in the operation of the machine is reached, the member 38 will have been rocked to a positionopposite to that in which it is illustrated in'Fig. 2. This change in the position of the member 38 brings its one "end into the path of the slidable member .28. Thus, as the carriers approach said extreme inner positions, the member 38 will engage the till latch 3% and will "force theend 33 thereof downwardly into locking engagement with" the hook 32. At the same time, the end 3;

of the lb'cking late- 11 34 will be moved out of connection with the hook 32 asthis disconnection of the end 33 from the hook 2 32 takes place, theinclmed end surface 36 mil enert a cain'ming action upon the inclined,

end 37 and Consequently will force the member 29 toward'tlie left in Fig. 2. This will rock the arm 25 upon its pivot and will shift tliel'rod 2S toward'the right and back to a position ready to be ei'igaged by the member 38 attthe' proper time. As the operation of the loom now continues, the shuttle will be drinvn to the right by the carrier 17 until it reaches its extreme outer position and will then be shifed back to the position shown in Fig. 2, where it becomes disconnected from the 'cal'rierl'i' and connected with the carrier in the manner set forth. These opei'iiticms are repeated in sequence through out any given operative period of the loom.

In the form illustrated in the drawings, a positive conl'iection is maintained between the shuttle and the actiiating mechanism, through the entire operative paths, of said shuttle. That is to say, throughout hall of a given path in one direction and a half of given path in the return direction, the shuttle'is in positive connection with one carrier and throughout the other half of said paths, is in positive connection with the other carrier. The shuttle is thus posw itively controlled throughout its entire range of inovetnent and consequently is uniformly moved and is free from undesirable variations in speed and at-the same time is positively maintained in its intended paths.

Various changes in the specitic form shown and described maybe made within the scope of the claims withoutdeparting from thespirit of the invention.

I claim: c

1, A loom comprising a stationary support, [a travelling shuttle, guiding devices on said support'extending over the operative paths of said shuttle, a pair of carriers arranged to be inversely reciprocated upon said guiding devices for passing said Shuttle overfsaid operative paths, a pivoted lever on said shuttle constituting a locking latch, hooks tixed upon said carriers, tripping devices mounted upon said carriers, and mechanism independent of said carriers for actuating the tripping devices of said carriers in alternate sequence whereby said lever is rocked at a predetermined point in the operative paths of said shuttle to connect it with one of said hooks and simultaneously disconnect it from the Oi llGPllflOli.

52. A loom comprising a stationary support, a travelling shuttle, guiding devices on said support extending over the operative paths of said shuttle, a pairot carriers arranged to be inversely reciprdcated upon 3.
